AFib after pacemaker

I'm sorry to see you have this development. Why did you have a pacemaker installed? It should control heart rate, but not cause AF. It seems to me you have had another development, or one revealed when the pacemaker was put in place, which sometimes happens. You might still need, and profit from, a catheter ablation.

Are you seeing an electrophysiologist? I would assume so because you have the pacemaker. Let that person know ASAP.

Had high heart rate. Had Afib once in a while. Never had it nonstop. Dr meds haven’t helped

But heart rate and blood pressure are very good.

I had paroxysmal Afib. My cardiologist put me on Amiodarone. That did stop the Afib but also put me into bradycardia. My heart rate was in the 30's, and I passed out. I then received a pacemaker which has controlled my heart rate well. However, after 1 1/2 years with the pacemaker, I went into Afib. I spontaneously converted after a month. A year later I was in persistent Afib for 3 months. I had a cardioversion and am now on Flecainide daily to (hopefully) prevent another episode. Your electrophysiologist will determine the best course of action for you. I resisted the cardioversion because I know so many people for whom it did not work. However, it has been 5 months since I had it, and I have not had another episode. If your pacemaker is monitored, your electrophysiologist knows when you are in Afib. They called me both times I went into Afib after my pacemaker. As gloaming said, you may need a catheter ablation. I was surprised when I went into Afib the first time because I thought the pacemaker would prevent that happening. Obviously, it does not. Good luck!

Very helpful. Thanks.

The pacemaker is not used for Afib. I believe Afib is a not uncommon side effect after pacemaker surgery. https://pmc.ncbi.nlm.nih.gov/articles/PMC6221846/
